Identiv uTrust 3700 F Contactless Smart Card Reader - NFC Ready

In this review of the Identiv uTrust 3700 F the bottom line is clear: this compact contactless reader is aimed at IT teams and front-desk environments that need reliable, fast NFC and 13.56 MHz contactless credential handling. The reviewer found the uTrust 3700 F particularly useful where mixed credential populations exist - ID-1 cards, tokens and NFC-enabled phones - because it combines broad protocol support, Windows plug-and-play convenience and in-field firmware upgradeability to reduce transaction time and long-term maintenance.

Key Features

• Contactless + NFC: Combines 13.56 MHz contactless technology and full NFC capability so the same reader handles traditional cards and mobile credentials.
• Mixed credential support: Works with ID-1 cards, tokens and NFC-enabled smart phones to simplify deployments that include different credential types.
• Keyboard emulation: Optional tray app can read a tag's UID or CSN and insert it as a string into host applications to speed data entry in legacy systems.
• Standards compatibility: Supports ISO/IEC 14443 and common card families such as MIFARE, DESFire and NTAG for broad interoperability.
• Plug-and-play drivers: Windows plug-and-play support and Identiv drivers make integration into PC-linked environments straightforward for administrators.
• Firmware upgrades: In-field firmware upgrade capability keeps the device current without replacing hardware, extending usable life.

Who It's For

The uTrust 3700 F is best for enterprise IT departments, reception desks, kiosks and POS stations that need a compact, reliable reader to accept a wide range of contactless credentials and NFC devices. Its keyboard emulation and Windows driver support make it a practical choice where quick integration into existing host software is required.

Those who should look elsewhere include buyers who need contact readers for physical access control with specialized mounting or sealed outdoor housings, or users who require integrated biometric or contact-based smart card interfaces beyond contactless/NFC functionality.

Pros & Cons

Pros

• Handles both contactless cards and NFC-enabled phones, reducing the need for multiple readers.
• Broad protocol support, including MIFARE, DESFire and NTAG families, ensures compatibility across many credential types.
